Memgraph
Memgraph is an in-memory graph database platform for graph computations on streaming data. It supports Cypher and lists Kafka, Pulsar, and Redpanda as streaming connectors. Its free Community Edition includes ACID transactions, on-disk persistence, high-availability replication, and vector search. MAGE adds more than 60 graph algorithms, with integrations for NetworkX, igraph, and cuGraph. Memgraph Lab provides a visual interface for querying, managing, importing, and visualizing graph data; it also supports natural-language queries through GraphChat. Programmatic drivers are listed for Python, C/C++, Rust, Node.js, C#, Go, Haskell, Java, JavaScript, PHP, and Ruby. Enterprise features include role- and label-based access controls, SSO, LDAP/PAM authentication, TLS encryption in transit, audit logging, failover, replication, disaster recovery, no-downtime updates, and monitoring. Community support is available through Discord; Enterprise includes direct engineering support through a dedicated Slack channel. Memgraph Cloud is managed and hosted on AWS in six regions, with instances from 1 GB to 32 GB RAM. Community Edition is free forever. Enterprise plans have unlisted prices that scale by memory capacity or graph data capacity, depending on the edition, and the Enterprise trial lasts 30 days.
NebulaGraph
NebulaGraph is a distributed graph database for storing and querying complex connected data. It is designed for scalability and millisecond responses to complex queries; the project says it can store and process graphs with trillions of edges and vertices. It supports nGQL and openCypher compatibility, while native ISO-GQL is supported in Enterprise v5.0. Native vector search combines graph structures with unstructured data. Deployment options include on-premises, public cloud, and hybrid environments, and NebulaGraph Cloud can deploy clusters on Azure, AWS, and Google Cloud Platform. Developers can use Java, Python, C++, and Go clients, plus Spark and Flink connectors. NebulaGraph Studio is a web-based tool for schema creation, data import, query writing, and graph exploration. Cloud features include Private Link, role-based graph-space permissions, Raft-based redundant backups across server rooms in the same city, and point-in-time snapshots. The open-source edition is free under Apache 2.0; a 14-day Cloud trial includes one instance with 2 vCPUs, 4 GB RAM, and 10 GB storage without payment information.
